14 Claims.

This invention relates to fasteners, and more particularly to an improved fastener slide for detachably holding the parallel ends of a gathering-cord, which passes around the collar of a life saving suit, in any desired adjusted position.

One object of the invention is to provide a" double cord fastener of the above nature cornprising a metal plate bent up into U-shape and provided with apair of inclined wedge slots in its side wings for receiving a gord-engaging wedge Figure 7 is a front view of thewedging roller shown in detached position, 7 v

roller which has a pair of manipulating knobs outside of said wings.

Another object is to provide a self-tightening detachable fastener slide of the above nature in which in which the side wings are provided with outwardly curled sections to facilitatethe A still further object is to providea device of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, ornamental in appearance, and very efficient and durable. in

use.

With these and other objects in view there have been illustrated on the accompanying drawings five forms in which the invention may be conveniently embodied in practice.

In the drawings:

Figur 1 represents a perspective view of a life saving suit having an adjustable collar-tightening cord, the two depending exterior portions of which are adapted to be detachably locked by a fastener slide embodying the present invention.

Figure 2 is a perspective view of the fastener slide as it appears in use for clamping the two exterior cord portions together.

Figure 4 is a side view of the same.

Figure 5 is a top view of the same on a larger scale, with the two cord portions shown in dotted outline.

Figure 6 is a development view of the flat blank from which the U asha'ped fastener slide is formed by bending.

Figure 11 is a development View of the flat blank, from which the second form of slide member, shown in Figures 8-10, is formed.

Figure 12 is a front view of a third form of fastener slide member having a. curved leaf spring for keeping the roller in contact .with. theparallel portions of the cord at all times.

Figure 19 is a detail side sectional view of the same, on an enlarged scale.

Referring now to the drawings in which like reference numeralg denote corresponding parts throughout the several views, the numeral [10 in: dicates the central baseportion of the U '-'s ha'ped slide A, and the numerals I l and I2 indicate the side wings thereof. Each of said side wings is provided in its central portion with an inclined sl'ot l3, l4, res ectively", which'slots are initially divergent when in the blank form as shown in Figure 6, but become parallel when b'entup into final form as 'shown'inFig'ures 21-and 4'. The side wings ll an'd'12are each provided withtwo pairs of outer end ears 'l5,'l6,'anu l1, l8, respectively, which ears are bentinwar'dly at right angles to form four straight lugs'for holding the exterior ortions 24 and 25 or the cord from slipping out "or ositionin the fastener member A;

The side wings/H and 'l 2 are also provided with two'pairs of inner endearsl9; 2ii,"and 2|, 22,respe'ctively, which are-bent outwardly and curled overt'o engage the exteriorof the side wings H and I2, said curled ears serving to guide the portions 24 and 25 of the cord smoothly when the slide A is moved up or down thereon.

The attaching cord is indicated generally by the numeral 23, and is adapted to have its parallel exterior portions 24 and 25 forced against the base NJ of the U-shaped member by the action of a crosswise wedging roller 26 which preferably has longitudinal corrugations on the surface thereof, as shown.

In order to permit the wedging roller 26 to be manually moved upwardly in the slots I3 and I4 away from the base Ill into unlocking position, provision is made of a pair of cylindrical heads- 21, 28 formed on the extremities of said wedging roller, said heads terminating in a pair of outer domes 29, 30.

While the present invention may be employed whenever it is necessary to'detachably lock two parallel cord portions or two separate cords together, it is especially adapted for us upon the exterior portions of a collar-gathering cord for tightening and holding the col1ar 3lla of a life saving suit 3| around the wearers neck 32, which cord is threaded through suitable slits 33 in said collar 30a of said suit 3!, whereby said collar 39a will have awatertight'fit around the wearers neck. It will be understood, however, that the improved fastener slide may be employed for holding the double gathering cord of any other article having a collapsible bag-like mouth.

Operation In operation, thecollar 30a of the suit 3| will be gathered and held firmly in water-tight condition about the neck 32 of the wearer by grasping the two bottom portions 24, 25 of the cord with one hand and pushing up the slide member A with the other hand as far as necessary.

The collar 30a. may also be gathered and tightened merely by pulling the two bottom cord portions 24, 25 apart, with both hands, which will cause the slide member A to move upwardly automatically to the desired point.

After the slide member. A..has been moved to the proper adjusted position, the automatic wedging action of the roller 26 will thereafter become eifective to prevent the collar from opening until desired. The wedging roller may, however, be released at any time merely. by grasping the knob ends 29, 30 thereof. and pulling said roller downwardly.

Modified forms In the second form of the invention shown in Figures 8-11, the cord portions 24 and 25 will be separated above the slide A so as to prevent the gathered material of the collar 35a. from wedging between said portions as the slide is moved upwardly. y

In this form of the invention, the lower part of the slide A is identical with that of the first form of slide A shown in Figures 1-7, but the upper part of said slide A is provided with a separating T-shaped spreader member 35 which is integrally connected to the base Illa by a neck 36, which in turn is connected to a tongue 31 having a pair of curved ears 38, 38. The side wings Ila and 12a of this form of the invention are provided with a pair of elongated inner tongues 39, 39 which are adapted to be curled outwardly and then inwardly, terminating at points spaced from the upper end of the slide. The tongue 31 is adapted to be bent upwardly so that the curved ears 38, 38 thereof will spread the cord portions 24, 25, outwardly from the sides 2,349,114 I T I .i

of the slide member instead of permitting them to emerge from the top of the slide in parallel contact as in the first form of the invention.

Provision is also made of a pair of outer elongated ears 40, 40 which are bent inwardly at their mid-points at right angles to the wings Ha and l2a to form lugs similar to the lugs l5 and I! of the first form of the invention.

By means of this construction, the portions 24 and 25 of the cord will be caused to enter the slide A at the top thereof throughopenings in the side wings I la and I2a, thus avoiding the forma- I tion of sharp angles in the cord sections which might produce chafing in the cord.

The third form of the invention shown in Figures 12 and 13 is identical with the second form shown in Figures 8-11 except that provision is made of a curved roller-pressing leaf spring 4| having extremities 42, 43 bent up around the straight ears IS, IT, and 40, 40, respectively. The leaf spring 4| serves to exert pressure upon the wedge roller 26 to keep it in engagement with the parallel cord portions 24 and 25 at all times.

Figures 14-16 illustrate the fourth form of the invention in which a short curved leaf spring 44 is employed, one end 45 of which is bent over upon the upper lugs 40, 40, and the lower end 46 of which is provided with a semi-circular socket 41 to engage the wedge roller 26.

Figures 17-19 illustrate the fifth form of the invention in which a pair of blocks 48 and 49 slidably mounted in the inclined slots 13a, I4a of the U-shaped fastener member A are pressed by a pair of coilsprings 50, 5| against the wedge roller 26. The springs50 and 5| are guided by a pair of pins 52, 53 formed on the blocks 48,49 and the outer ends ofsaid slots l3-a, I4a, respectively.

While there have been disclosed in this specification several forms in which the invention may be embodied, it is to be understood that these forms are shown for the purpose of illustration only, and-that the invention is not to be limited to the specific disclosure, but -may be modified and embodied in various other forms without'departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.
